Also, the thickness should be three or four millimeters. Keeping the thickness in check is very important if you wish to make seal durable enough.

Thread Sealant Application

You need to put the tape sealant on male pipe. And so, start wrapping the tape in a direction following thread. This basically means going clockwise.

Then gradually put male pipe inside the female pipe. Get a good quality adjustable wrench. You need to use this for tightening the pipes together. But be very careful while tightening both pipes. It should not be too forceful to cause a break. Now finally, do a check on both pipes in case there is a leakage noticeable.

In Case the Pipe is Exposed to Extreme Temperature

Sometimes using just, the pipe thread sealant tape is not enough. And so, you may need to use the other pipe dope type next. This is basically the case when pipe has to deal with extreme temperatures.

To use the dope, you need to make sure there’s no dirt or debris making any mess in both male and female pipe threads. Also, be wary of clearing any oil from these parts. Now use a generous amount of dope to apply thoroughly onto the male threads. You can use a brush applicator that usually comes with it for coating nicely.

Then gradually connect it to the female pipe. The connected pipe may have some oozes out. In such a case, you should clear out any excess to have a smooth end result. Let the thing dry evenly. And finally, check again for any leaks and also make sure it’s watertight.
